Product Name:Cyclic Olefin Copolymer
English Name:Cyclic Olefin Copolymer
CAS No.:26007-43-2
Aliases:COC, Cycloolefin copolymer
Molecular Formula:(C8H12·C2H4)n
Physical Properties:An amorphous thermoplastic resin with high transparency, low birefringence, low moisture absorption, and excellent dimensional stability. It offers good chemical resistance, high light transmittance, a wide glass transition temperature range (approximately 70–180°C), and a density of about 1.01–1.03 g/cm³.
Uses:Used to manufacture precision optical components such as camera lenses, CD/DVD pickup lenses, and laser printer lenses. Also used in blister packaging (PTP) films, optical films, medical devices, and electronic components. Its low birefringence and high light transmittance meet optical imaging requirements, while low moisture absorption helps maintain dimensional stability.
Technical Specifications:
Light transmittance is approximately 91%–93%.
Glass transition temperature is approximately 70–180°C, depending on grade.
Water absorption is less than 0.01%.
Density is approximately 1.01–1.03 g/cm³.
Refractive index is approximately 1.53.
